The biggest fear of people nowadays is seeing the Low Battery warning on their mobiles. Mobiles have become an integral part of our lives. They are important to us. But they are battery based; they need charging regularly.
The black and white old mobiles used to last a week on one charge. Now with technology, there are portable chargers! You can charge your mobiles on the go. The portable chargers or power banks are now easily available.
Unfortunately, most of us do not know what a power bank is and how it works. Even the manufacturers or sellers do not feel the need to educate the buyers on this necessary information. There are some points to be taken care of while choosing a good power bank depending on your device.
Capacity: This is the most important deciding point in the choice of a right power bank. Power Bank capacity refers to how much charge is inside a power bank battery. It is measured in mAh or milliamps per hour. But one thing you need to understand that when a power bank is charging your smartphone or tablet, some of the energy is lost in the transfer of power. So the real capacity is about 60-65 percent of the battery capacity listed on the power bank. For example, a power bank with battery capacity at 2200 mAh has real capabilities in the range 1320mAh to 1430mAh. And this is for quality battery, for a downgraded battery the loss of power is even more, and hence the real capacity would be less than 1320mAh. Should you decide to buy a power bank, keep your usage in mind. To meet ever-growing charging needs of users, many higher mAh units are available today. More Top end power banks can charge almost any type of devices, from laptops, iPads, tablets and smartphones.
Connectors: Pay specific attention to the number of connectors and the type of connector. It would be more advisable to go for a power bank with built-in cable.
Portability: We are buying a power bank because of its portable nature. If you have to carry a huge power bank than your device, it is too impractical.
Price: Power banks which promise higher capacity at a substantially lower price may not be genuine. Most of them use refurbished battery and may not last long. Go for a power bank from a well-known brand. Though it may be a bit expensive, it will keep your device safe and give the required performance.
Protective Circuitry: Ensure that your power bank has additional features to protect your device. Pay attention to following –
Short Circuit Protection – This will help keep your power bank and the device safe when the short circuit problems happen.
Over Charging Protection – This feature will let the power bank cut off the supply when your device is charged fully. Thus, it will be useful in cases of the device being left for charging and forgotten.
Temperature Protection – This will help identify the cases of device overheating while charging the device.
Certification: Check for the UL certification of the device. It will ensure that the power bank you have been buying meets all standard quality requirements.

Power Bank Troubleshooting
Power bank does not charge my device: If you are trying to charge your tablet, you should use 2A port. Most of the tablets do not charge via 1A port.
Power bank battery drains very faster: Do not keep the cables attached to the power bank when not in use. Such a practice drains the battery. Recheck the battery capacity of your device and power bank you are using. Remember to use correct connectors to avoid loss of charge.
Power bank does not turn on: Your power bank might have drained out thoroughly. Put it to charge and check whether it charges and then try switching it on. Some power banks go into sleep mode in case of overcharge/over discharge/short circuit. In most of the cases, this happens due to faulty cables. Replace cables and check.
